MacOS is the same sort of walled garden as Windows though. It has plenty of dark patterns in stuff like iCloud too, I imagine with some more years of enshittification it will be in a similar state to Windows today.

And corporate customers like the French government will want their users to be within strictly controlled environments - walled gardens. That's why they've used Microsoft for so long. MacOS isn't as good for this scenario from what I understand, but is Linux?
